Just picked up 4 cams that have been out for a week. All of them are at zero meaning all pics have been taken. All cams are Owl PF, MS20, 12V 1.2Amp batt's. 2 cams with timer and 2 without. The 2 with timers (one-shot) are completely dead (batt ran to very low voltage) and the two w/out timers are still working fine with good voltage. Could the draw from the timer and PIR be too much for the 12V batt to handle? I made sure each batt was fresh before I put them out. They were out a total of 1 week. I'm gonna put a fresh batt in one of them and put it in the closet. I'll check it each day and find out how long it's lasting. Seems kinda odd that I'm having a problem with the cams that have timers and not with the cams that don't. I'll let you in on the results once I know more. If this is gonna be a problem then I may be removing the timers.
